A little piece of the 1920s, reimagined in red. The Sonnet hexagon ruby engagement ring centers a six-sided, hexagon-cut lab-grown ruby — a genuine, richly saturated gem — inside an art-deco cluster of marquise and round simulated diamonds, all set in 14K rose gold vermeil over sterling silver 925. Geometric, warm and unmistakably vintage, it is made for anyone who wants their ring to carry a little heritage and a lot of color. See it among our ruby engagement rings.

The hexagon cut
The hexagon is one of the most characterful geometric cuts in fine jewelry — six clean sides and sharp angular edges that read as deliberately architectural rather than rounded. Next to the ovals, rounds and cushions that dominate the bridal aisle, a hexagon announces at a glance that this is not a conventional ring. The shape suits ruby especially well: its angled facets hold and pool light differently than curved cuts, deepening the stone’s red into concentrated flashes of color. Rooted in the art-deco era, the hexagon has surged back into favor with couples who have moved on from cookie-cutter solitaires and toward the character you will find across our ruby jewelry range.
The art-deco cluster setting
Wrapping the hexagon ruby is a symmetrical cluster of accent stones — marquise points on the outer edges flanked by round brilliants closer to the center, spreading like little wings on either side of the gem. A cluster (rather than a plain halo) is one of the most recognizably vintage design gestures, lending the ring genuine bridal presence while keeping every eye on the ruby. The effect is heritage-inspired and intentional, the opposite of contemporary minimalism.
The lab-grown ruby
The center stone is a genuine lab-grown ruby (roughly 5 x 9 mm, about 1.3 ct, AAA grade). Lab-grown ruby is real corundum — identical to mined ruby in chemistry, hardness and optics, with the same saturated red and the same remarkable 9 on the Mohs scale. What changes is only where it comes from: it is grown in a controlled setting over weeks rather than mined over millennia, which brings cleaner color, fewer inclusions, a gentler price and an ethical, conflict-free origin. It is a real ruby in every meaningful sense — never mined, never simulated. For the lore behind the stone, our guide to ruby meaning is well worth a read.
Simulated diamond accents
The marquise and round accents are simulated diamonds — bright, brilliant and beautifully affordable, chosen to give the cluster its vintage sparkle without overshadowing the ruby at its heart. Prefer moissanite or lab-grown diamond accents? Just ask and we will tailor it.
14K rose gold vermeil over sterling silver 925
The ring is crafted in 14K rose gold vermeil over sterling silver 925 — a genuine layer of real rose gold bonded to a solid sterling silver base. Rose gold’s warm, copper-pink tone sits right beside ruby-red on the color wheel, so metal and stone read as one harmonious, romantic whole. It flatters a wide range of skin tones and delivers the glow of fine rose gold at a far more welcoming price.
What ruby symbolizes
Crowned the “king of gemstones” for over two thousand years, ruby has always stood for passion, courage, vitality and devoted love — its color, quite literally, the color of the heart. That depth of meaning is why it makes such a resonant engagement stone, why couples love matching sets from our ruby couples rings collection, and why it remains the classic gift for 15th and 40th anniversaries. If a red ring speaks your language, our journal on red engagement rings and our garnet vs ruby comparison will help you choose with confidence.

Aquamarise vermeil is real gold over sterling silver 925 — the rich, golden look you love, at a price that makes it easy to say yes.

The same design is also available in solid gold.
Sizing & care
Choose your size at checkout. If you are between sizes or unsure, we are glad to help — and if the fit is not quite right, resizing is available and starts from a modest fee (the cluster setting adds a little complexity, so a skilled jeweler is ideal). Store the ring in its velvet box between wears and buff gently with a soft, dry cloth to keep the ruby and rose gold bright. Ruby is one of the hardest-wearing colored stones you can choose — as our guide to the July birthstone explains, it is built for everyday life.
Frequently asked questions
Is the ruby real?
Yes. The center stone is a genuine lab-grown ruby — real corundum, identical to mined ruby in chemistry, hardness and optics, with the same saturated red and the same 9 Mohs hardness. It is grown in a controlled setting rather than mined, which is what keeps its color clean and its price friendly. A real ruby, never a simulant.
What does AAA grade mean for ruby?
AAA is the top commercial quality tier — deep, even red color, strong clarity and a precise cut. At lab-grown AAA grade you get that top color story without the price premium a mined AAA ruby would command.
Why a hexagon cut?
The hexagon is a six-sided geometric cut with sharp angular edges, deliberately architectural rather than rounded. It suits ruby beautifully because the angled facets hold and pool light, deepening the red into concentrated flashes of color — and it signals at a glance that this is not a conventional bridal piece.
Is this a halo or a cluster ring?
It is a cluster ring. A halo wraps the center stone in one continuous frame of small stones, while this design uses a symmetrical arrangement of marquise and round accents that spread like wings on either side of the ruby — a distinctly vintage, art-deco gesture.
What are the accent stones?
Simulated diamonds — bright, brilliant and budget-friendly, chosen to give the cluster its sparkle without overshadowing the ruby. If you would prefer moissanite or lab-grown diamond accents, reach out and we will tailor it.
What metal is it made from?
14K rose gold vermeil over sterling silver 925 — a genuine layer of real rose gold over a solid sterling silver base, for the warm glow of fine rose gold at a friendlier price.
What is rose gold vermeil?
Rose gold vermeil is real 14K rose gold over sterling silver 925 — the look and warmth of gold at a price that is far easier to say yes to. If you would like gold all the way through, the same design is also available in solid gold.
Is ruby durable enough for daily wear?
Very. Ruby rates 9 on the Mohs scale, second only to diamond among engagement-ring stones and in the same family as sapphire. It handles everyday wear beautifully, even for active hands.
Is ruby a July birthstone?
Yes. Ruby is the traditional July birthstone, which makes this ring an especially meaningful July birthday gift — and it is the classic stone for 15th and 40th anniversaries too.
Why rose gold for a ruby ring?
Rose gold’s warm, copper-pink tone sits right beside ruby-red on the color wheel, so metal and stone form one cohesive, romantic color story rather than a stark contrast. It also flatters a wide range of skin tones.
Can this ring be resized?
Yes, within reason. Choose your size at checkout, and if the fit is not right, resizing is available and starts from a modest fee. Because the cluster setting adds some complexity, a skilled jeweler is the safest choice.
Is it nickel-free?
Yes. The sterling silver base and the rose gold vermeil layer are both nickel-free, making the ring a comfortable choice for sensitive skin.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
Can I wear it as a promise ring?
Absolutely. The slim 1.6 mm band and vintage cluster work just as well as a promise, anniversary or right-hand ring as they do as an engagement ring — and ruby’s link to devoted love makes it a meaningful promise stone.
